Fig. 1 is a schematic flow chart of a vehicle navigation voice broadcasting method provided in an embodiment of the present application. As shown in fig. 1, the vehicle navigation voice broadcasting method includes:

step 101, under the condition that the vehicle is started for navigation, navigation path information of a journey selected by a driver is obtained, wherein the navigation path information comprises journey types and journey stages.

In particular, navigation is a process of guiding a carrier from a starting point to a destination safely and reliably, wherein navigation parameters include the position, speed, attitude, direction, etc. of the carrier. In this application, the carrier is a vehicle, and navigation refers to in-vehicle navigation used on a vehicle. At present, navigation data of a vehicle navigation configuration mainly comprises the following contents: basic map display data including road network data, background data, name data, and the like; the user inputs guiding data obtained by searching the starting place and the destination, wherein the guiding data at least comprises lane information, image data information at the crossing, guideboard information, and building data information on the road and the vicinity thereof; traffic information data, namely the current congestion status of each road section in popular terms. In addition, the vehicle needs to be able to acquire positioning data, and to perform accurate positioning according to a global positioning system (Global Positioning System, GPS) and an inertial navigation system of the vehicle body, so as to acquire current position information. The navigation path information includes a start point, a destination, lane information, image information at an intersection, guideboard information, building information along a route such as toll booth information, and the like, and in addition, the navigation path information in the present application adds a journey category and a journey stage. The current travel is classified according to the whole distance of the current travel, and each travel type is divided into different travel stages. For example, the driver No. 1 selects a navigation path a for the present trip, and the present trip is classified into a short trip by a kilometer in the whole trip and two trip stages are respectively a short trip first stage and a short trip second stage for the short trip through corresponding calculation.

Under the condition that the vehicle starts navigation, when a driver inputs a starting place and a destination into the vehicle-mounted navigation, the vehicle calculates and recommends a plurality of feasible routes according to factors such as travel time or distance, the driver selects one route from the feasible routes to formally start navigation, and the navigation route information of the travel selected by the driver is obtained as an information basis for carrying out subsequent steps.

From the characteristics of the rhythm sound form and the spirit connotation thereof, the rhythm type is of a light and fast type, a heavy and heavy type, a hyperthermia type and the like.

For different journey stages, the one-to-one rhythm type can be set for the same, for example, the navigation voice broadcasting rhythm type for the first stage of short distance can be set to be light and fast, the navigation voice broadcasting rhythm type for the second stage of short distance can be set to be comfortable … … the one-to-one correspondence between journey stages and navigation broadcasting rhythms is not limited, and research and development related personnel can combine the possible rough moods of a driver in different journey stages to set a proper navigation broadcasting rhythm, so that the driver obtains more comfortable and pleasant driving experience. The current journey stage can be obtained in the steps, and then the first target broadcasting rhythm corresponding to the current journey stage is determined according to the corresponding relation between the set journey stage and the navigation broadcasting rhythm. By adding voice packets with different navigation broadcasting rhythm types, a user can obtain different personalized navigation broadcasting services at different driving stages, and the satisfaction degree of the user on vehicle navigation broadcasting is improved.

And 105, controlling the vehicle navigation voice broadcasting to broadcast in the current journey stage according to the first target broadcasting rhythm.

Specifically, after determining that the broadcasting rhythm corresponding to the current journey stage is the first target broadcasting rhythm, the vehicle navigation voice broadcasting in the current journey stage needs to be controlled to broadcast according to the first target broadcasting rhythm. Each broadcasting rhythm has a corresponding voice packet, the voice packets are stored in a local database of the vehicle, when the broadcasting rhythm corresponding to the current journey stage is determined to be a first target broadcasting rhythm, the first target voice packet corresponding to the first target broadcasting rhythm is called, and the audio rhythm in the first target voice packet is the first target broadcasting rhythm, so that the audio in the first target voice packet is selectively broadcasted in combination with the actual road condition.

Specifically, the driver can perform related selection operation on the selection mode of the navigation broadcasting rhythm during the driving process. The selection mode is that in different journey stages, a vehicle randomly selects one broadcasting rhythm in a preset navigation broadcasting rhythm list to broadcast, and the selection mode for randomly selecting the broadcasting rhythm has great randomness, because once the driver selects the selection mode, the driver cannot expect which broadcasting rhythm to navigate in the next stage is in the navigation broadcasting rhythm list. Another selection mode is to sequentially select a broadcasting rhythm from a preset navigation broadcasting rhythm list, for example, according to a corresponding relation between a preset travel stage and a navigation broadcasting rhythm, the navigation broadcasting rhythm corresponding to a long-distance first stage is a broadcasting rhythm a, the navigation broadcasting rhythm corresponding to a long-distance second stage is a broadcasting rhythm B, the navigation broadcasting rhythm corresponding to a long-distance third stage is a broadcasting rhythm C, the navigation broadcasting rhythm corresponding to a long-distance fourth stage is a broadcasting rhythm D, and the navigation broadcasting rhythm corresponding to a long-distance fifth stage is a broadcasting rhythm E. The preset distance varies according to the current travel, for example, the whole travel distance is 30 km, the travel type is a midway travel, and then the preset distance is 20 km; the whole distance of the journey is 200 km, the journey type is long distance journey, and then the preset distance is 40 km.

Receiving a selection operation of a driver for a selection mode of a navigation broadcasting rhythm, and playing corresponding broadcasting rhythms in different travel stages of vehicle running according to a corresponding relation between a preset travel stage and the navigation broadcasting rhythm under the condition that the selection mode selected by the driver is the sequential selection of the broadcasting rhythms from a preset navigation broadcasting rhythm list; under the condition that the selection mode selected by the driver is that broadcasting rhythms are randomly selected from the navigation broadcasting rhythms list, one navigation broadcasting rhythms are randomly selected from the navigation broadcasting rhythms list at preset distances at intervals to broadcast.

The vehicle receives a change instruction which is input by a driver and aims at the target broadcasting rhythm, the change instruction indicates that the navigation broadcasting rhythm of the current journey stage is changed into a third target broadcasting rhythm, and under the condition that a local database contains a third target voice packet corresponding to the third target broadcasting rhythm, the third target voice packet corresponding to the third target broadcasting rhythm in the local database is called, and the audio frequency rhythm in the third target voice packet is the third target broadcasting rhythm, so that the audio frequency in the third target voice packet is selectively broadcasted in combination with the actual road condition, and the vehicle navigation voice broadcasting rhythm of the current journey stage is changed into the third target broadcasting rhythm. The broadcasting rhythm of the current journey stage is flexibly changed by receiving the changing instruction, so that diversified requirements of a driver on the navigation voice broadcasting rhythm in the driving process are met, and satisfaction degree of a user on vehicle-mounted voice broadcasting is improved.

In some embodiments, after controlling the vehicle navigation voice broadcast to be broadcast with the second target broadcast rhythm in the current trip stage according to the change instruction, the method further includes:

under the condition that the driver reaches the trip end point of the selected trip, sending out inquiry information, wherein the inquiry information is used for inquiring whether the navigation broadcasting rhythm corresponding to the current trip stage in the corresponding relation is updated to be a second target broadcasting rhythm;

and under the condition that an affirmative instruction fed back by the driver based on the inquiry information is received, updating the navigation broadcasting rhythm corresponding to the current journey stage in the corresponding relation into a second target broadcasting rhythm.

Specifically, after broadcasting in the current journey stage with the second target broadcasting rhythm, when the journey end of the selected journey is reached, that is, when the current journey is ended, the vehicle sends out inquiry information for inquiring whether to change the corresponding relation between the journey stage and the navigation broadcasting rhythm, and when a positive instruction fed back by a driver based on the inquiry information is received, the corresponding relation between the preset journey stage and the navigation broadcasting rhythm is changed according to the relation between the journey stage and the navigation broadcasting rhythm in the journey, so that the corresponding relation between the changed journey stage and the navigation broadcasting rhythm adopted in the next journey is changed. For example, the corresponding relation between the preset trip stage and the navigation broadcasting rhythm is that the navigation broadcasting rhythm corresponding to the short-distance first stage is broadcasting rhythm G, the navigation broadcasting rhythm corresponding to the short-distance second stage is broadcasting rhythm H, in the trip, the navigation broadcasting rhythm is changed into broadcasting rhythm a in the driving process of the short-distance first stage, and then when a positive instruction fed back by a driver based on the inquiry information is received after the trip is finished, the corresponding relation between the trip stage and the navigation broadcasting rhythm is changed into the navigation broadcasting rhythm corresponding to the short-distance first stage is broadcasting rhythm a, and the navigation broadcasting rhythm corresponding to the short-distance second stage is broadcasting rhythm H. The corresponding relation between the travel stage and the navigation broadcasting rhythm is flexibly changed by receiving the changing instruction, so that the diversified requirements of a driver on the navigation voice broadcasting rhythm in the driving process are met, and the satisfaction degree of the user on the vehicle-mounted voice broadcasting is improved.

In some embodiments, a travel time of a vehicle is obtained; under the condition that the driving time length is longer than the preset time length, controlling the vehicle to broadcast reminding information according to the navigation broadcasting rhythm corresponding to the fifth long-distance stage; the reminding information is used for reminding the driver of stopping and resting.

Specifically, the application does not limit specific numerical values of the preset duration, and the research personnel select a reasonable numerical value according to actual test conditions. The long-time driving of the vehicle can consume the energy of the driver to be tired and can increase the physical burden for the driver, so that the driving time of the vehicle needs to be monitored in the driving process of the vehicle, and under the condition that the driving time is detected to be longer than the preset time, the driver is indicated to continuously drive for longer than the preset time, and the driver is possibly tired and insufficient, so that the vehicle is controlled to report reminding information for reminding the driver to stop and rest according to the navigation broadcasting rhythm corresponding to the fifth long-distance stage, and traffic accidents caused by fatigue driving are effectively avoided.
